Six graves / Angela Marsons.

It's a typical teenage bedroom with posters covering the walls and clothes littering the floor. But the girl lying on her bed, wearing a delicate chain around her neck, is lifeless. A circle of red stains her white vest top. How had the girl's mother looked down at her sleeping child and pulled the trigger? When Detective Kim Stone rushes to the scene of a house fire, she's shocked to discover it's claimed the lives of two teenage children and their parents. But this tragedy is not quite as it seems. Each body is marked by a gunshot wound and the mother, Helen Daynes, is holding the gun. The case sparks painful childhood memories for Kim who suffered at the hands of her own abusive mother, but it just makes her more determined to uncover the truth. As Kim untangles Helen's past, she finds a history of clinical depression. But did it drive Helen to murder her loved ones? Then Kim uncovers a tiny, vital clue in Helen's bedroom that throws the investigation wide open. Could someone else have killed the Daynes family? Just as Kim feels she's making progress, a deadly threat is made to her own life by a dangerous psychopath from her past. Biting back her fear, she keeps digging. And when Kim hits upon a shocking secret that changes everything she thought she knew about Helen, she realises that the remaining family members are in grave danger. Kim is under pressure like never before, and the monster circling her is getting ever closer. Four bodies already. Four graves fresh in the ground. Who will be next? Can Kim find the killer and save herself before it's too late?
